uNiTian COMBINATION KNIFE AND SAIV'.

To all whom it may concern:

Be it known that I, ALEXANDER HALL, a citizen of the United States,residing at Portsmouth, in the county of Scioto and State of Ohio, haveinvented certain new and useful Improvements in a Combination Knife andSaw, of which the following is a specification.

This invention relates to cutting devices and more particularly to acombination knife and saw and the primary object is to provide a knifeadapted for use in connection with a cutting block, the knife beingsuspended in a manner that will permit it to be reciprocated' or raisedand lowered as desired.

Other objects of the invention will appear upon consideration ofthefollowing detail description and accompanying drawings, whereinFigure 1 is a side elevation of the device constructed in accordancewith my invention, and a Fig. 2 i an end elevation of the same.

Referring to the drawing by numerals, the base block 1 is ofsubstantially rectangular form and of any desired thickness. Arrangednear one end of the base 1 and ex tending upwardly therefrom is a hangerwhich consists of the parallel uprights 2 and 3 the lower ends of whichare extended through openings formed in the base block. Recesses 1 inthe bottom of the base block communicate with the openings for thestandards so that fastening nuts 5 may be screw threadedly mounted onthe lower ends of the standards to secure them in position. The top ofthe block is engaged by nuts 6 carried by the standards 2 and 3 directlyadjacent the block so that the desired adjustment may be obtained whenthe standards 2 and 3 are raised and lowered. The upper ends of thestandards as shown to advantage in Fig. 2 are curved inwardly towardeach other to provide substantially U-shaped inverted brackets 7, themeeting ends of which are provided with openings to receive a pivot bolt8. Mounted upon the pivot bolt 8 is a hanger rod 9 which is providedwith two screw threaded rod sections connected together by a turn buckle10. The lower section is provided with a bifurcated end adapted to bepivotally connected as indicated at 12 to one end of the cutting knife13. The cutting knife is provided with a cutting edge 14 and a saw edge15 so that the knife Specification of Letters Patent.

may be employed for both chopping, cutting and sawing. The knife at theend opposite to the pivoted portion is provided with a handle memberwhich may be gripped by the operator to permit proper manipulation ofthe knife when it is in use. it will he notes from this constructionthat the knife may be raised and lowered and also may be reciprocatedlongitudinally with respect to the block to accomplish the cutting ofany material placed upon the block beneath the knife.

To prevent reciprocation of the knife when it is used as a choppingmember, a latch 16 is provided which consists of a bar pivotallyconnected to one of the upright members as indicated at 17 and adaptedto be releasably connected to the other upright member .as shown in Fig.2. This bar, will engage the hanger rod 9 so that sliding movement ofthe knife will be prevented but will not prohibit the knife from beingraised and lowered when chopping.

Minor changes may be made in the details of construction withoutdeparting from the spirit of the invention or the scope of the claimshereunto appended.

What is claimed is 1. In a device of the character described,

'a base block. upright standards mounted at one end of the base blockand having their upper terminals provided with inverted U- shapedbracket members, the ends of the said bracket members being arranged inclose proximity, a pivot member carried by the said meeting ends of thebracket members, a hanger rod suspended from the said pivot member, anda cutting element carried by the lower end of the said hanger rod anddapted to extend across the surface of the said block.

2. In a device of the character described, a base block, a supportingmember mounted at one end of the base block and including spaceduprights, the upper ends of the said uprights being curved toward eachother to provide brackets, the meeting ends of the brackets beingdisposed centrally with re spect to the space between the said uprightmembers, a suspension hanger, means to pivotally connect the said hangerto the meeting ends of the said brackets, and a cutting knife connectedto the lower end of the hanger.

3. In a device of the character described, a base block, a supportingmember mounted at one end of the base block and including spaceduprights, the upper ends of the said uprights being curved toward eachother to provide brackets, the meeting ends of the brackets beingdisposed centrally with respect to the space between the said uprightmembers, a suspension hanger, means to pivotally connect the said hangerto the meeting ends of the said brackets, and a cutting knife connectedto the lower end of the hanger, the said cutting knife being adapted toextend parallel with respect to the flat surface of the said block andmeans carried by the upright members to be disposed in a position forengaging the said suspension 15 hanger whereby swinging movement of thelatter will be prevented.

In testimony whereof, I have aflixed my signature in the presence of twoWitnesses.
